Ann Romney told CNN on Thursday that she is still "done" with the idea of another presidential bid, but adds "you know, you never do say never."

"At this point in time, that's where we are mentally is done," Romney said on CNN's "New Day" on Thursday morning, when asked about the possibility of her husband Mitt Romney seeking a third presidential bid.

And she said her husband is "absolutely" in the same mindset.

That interview came after she said her family was, "Done. Done. Done" with her husband's presidential ambitions in an interview with the Los Angeles Times published Monday.

But Romney said Thursday on CNN that "we never say never" and that the country would be in a better place if her husband were president, calling him "one competent guy who really is a great leader."

Sen. Bernie Sanders, one of the Senate's leading doves, said Tuesday he doesn't want the United States leading the fight against ISIS. Instead, said the Vermont senator, who is eyeing a 2016 presidential bid, the nation should be focused on helping the middle class.

Sanders, an Independent who caucuses with Democrats, said he doesn't want to see the United States fall into another "quagmire in the Middle East," and he put the onus on Muslim countries to take on ISIS.

"I'm sitting here wondering where Saudi Arabia is, where Kuwait is, where Qatar is," Sanders said on CNN's "New Day." "I'll be damned if kids in the state of Vermont - or taxpayers in the state of Vermont - have to defend the royal Saudi family, which is worth hundreds of billions of dollars."

Saudi Arabia and Qatar are part of a five-country coalition of Middle Eastern nations that have joined the U.S. in airstrikes against ISIS in Syria, but Sanders suggested the U.S. should only be "supportive."

Sanders also joined 21 other senators earlier this month in opposing a resolution to train and arm 5,000 moderate Syrian rebels to combat ISIS.

"It cannot be won and it will not be won by the United States alone," Sanders said of the war on ISIS.

Sen. John McCain slammed President Barack Obama on Monday over his comments that U.S. intelligence underestimated ISIS.

McCain countered Obama's assertions made on CBS' "60 Minutes," saying that ISIS' expansion in Syria and Iraq was tied to the President's decision not to leave a residual U.S. military force in Iraq and his refusal to arm moderate Syrian rebels last year despite urgings from his national security advisers.

"We predicted this and watched it," McCain said on CNN's "New Day." "It was like watching a train wreck and warning every step of the way that this was happening."

In the "60 Minutes" interview that aired Sunday, Obama admitted that a chaotic Syria became "ground zero for jihadists around the world" and that the United States also underestimated the strength of Iraqi security forces.

The Republican senator from Arizona also reserved some criticism for his fellow legislators who went on recess to focus on the November midterm elections without voting on U.S. military action in Syria.

"It's an act of cowardice on the part of Congress," McCain said. "They didn't want to vote before the election."

After adjourning without a vote more than a week earlier, House Speaker John Boehner told ABC News on Sunday that he would be "happy" to call lawmakers back to the House floor for a vote if Obama submits a resolution to Congress.

"I'd bring the Congress back," Boehner said.

Rep. Ed Royce, chairman of the House Foreign Affairs Committee, criticized the President for his "political failure" rather than a failure of the intelligence community, saying Obama needs to lead.

"It is incumbent upon the commander in chief to lay out the strategy that he wants," Royce said. "We have given him those tools."

McCain also called on the Obama administration to take on Syrian President Bashar al-Assad's regime, renewing calls for a no-fly zone over Syria and saying the United States should "take out his air force" if the Syrian ruler doesn't keep his planes out of the air.

McCain said Obama has the authority to attack al-Assad's regime without congressional authorization and said not doing so would be "immoral."

"They want to train 5,000 Free Syrian Army people in Saudi Arabia and send them back. But are we going to do anything about Bashar al-Assad's air attacks?" McCain said. "Are you going to ask these young people ... to fight against ISIS but not against Assad. It's not only unworkable, it's immoral."

McCain and fellow hawk Sen. Lindsey Graham, R-South Carolina, first advocated for a no-fly zone in Syria in the summer of 2013 when Obama was considering military action against the Syrian regime, which McCain said is responsible for the death of 192,000 Syrians.

McCain agreed with the Obama administration that the United States is at war with ISIS - a statement that only 40% of Americans agree with, according to a CNN/ORC International poll released Monday.
